Initial Value:

Final Value:

The percentage increase calculator helps you find how much a number has increased in percentage. Percentage increase tells you the difference between the initial and final values as a percentage. For example, if your monthly salary went up from 1000 to 2000, this calculator will tell you the percentage increase in your salary.

Formula and explanation

To calculate the percentage increase, this calculator uses a simple mathematical formula:

Percentage Increase = [(New Value – Old Value) / Old Value] × 100

The first step you need to take is to figure out how much the value has increased. To do this, subtract the initial value from the final value. This will give you an absolute increase. The formula for this calculation is Difference = New Value − Original Value.

Once you know the difference between initial and final values, you need to figure out what percentage of the original value this increase represents. To find this value, divide the difference by the original (final value) value. Proportion = Difference/Original Value.

Example 1:
Salary Increase – $500 to $600
Difference – $600 – $500 = $100
Proportion – $100 ÷ $500 = 0.2
Percentage – 0.2 × 100 = 20%
Salary increased by 20%.

Example 2:
Groceries – $40 to $50
Difference – $50 – $40 = $10
Proportion – $10 ÷ $40 = 0.25
Percentage – 0.25 × 100 = 25%
Groceries increased by 25% .

The final step in the calculation is to convert proportions to percentages, which can be done by multiplying them by 100. The formula for this calculation is: Percentage Increase = Proportion x 100.

Initial Value	Final Value	% Increase	Absolute Difference	Multiplier Factor
100	110	10%	10	1.1
200	230	15%	30	1.15
500	600	20%	100	1.2
1000	1250	25%	250	1.25
2000	2600	30%	600	1.3
5000	6750	35%	1750	1.35
7500	10500	40%	3000	1.4
10000	15000	50%	5000	1.5
15000	24000	60%	9000	1.6
20000	35000	75%	15000	1.75
